trying to swap over from a BSPT male line to an NPT port, is this the right adapter for that?
Answer by: Customer Support on Jan 19, 2026, 1:06 PM
For converting thread types, it’s a straight steel adapter with a male BSPT on one side and a female NPTF on the other. Both ends are 1-1/2 inch, with Side 1 called out as R 1-1/2 - 11 and Side 2 called out as 1-1/2 - 11.5 NPTF.
